Complex Network Based Role Attribution in International and Intersectoral Trade — •Julian Maluck and Reik V. Donner — Potsdam Institute for Climate Impact Research, Germany

Supply chains in contemporary economy result in a complex network of trade relationships with a highly non-trivial topology. Multi-regional input-output tables summarize the monetary flows between industry sectors and can be meaningfully interpreted as a weighted and directed network of interacting subgraphs. We show that complex network theory provides sophisticated methods to attribute characteristic roles to industry sectors and countries. Specifically, in a directed network different patterns of clustering coefficients are attributed to different roles in the supply chain. In order to evaluate the robustness of trade relationships we introduce a generalization of the Hamming distance to weighted networks. In addition, we discuss how further standard network measures can be adapted on an economically meaningful way for studying the network properties of global trade.
